  • Patent number: 8679859
    Abstract: Devices comprising functionalized materials, and embodiments of a method for making and using such devices, are disclosed. Exemplary devices include ophthalmic devices, nanoparticles, quartz crystal microbalances, microarrays, and nanocomposites. In particular embodiments, device surfaces are modified with monomers and/or polymers, typically carbohydrate monomers and/or polymers. Embodiments of a method for making and using such devices are disclosed. Monomers and/or polymers are covalently bonded to surfaces using functionalized perhalophenylazides. In some embodiments, device surfaces are functionalized with a perhalophenylazide. One or more monomers and/or polymers subsequently are covalently bonded to the device surface using the perhalophenylazide. In other embodiments, monomers and/or polymers are derivatized with a functionalized perhalophenylazide. The derivatized monomers and/or polymers then are covalently bonded to the device surface using the perhalophenylazide.

  • Publication number: 20050027102
    Abstract: Molecularly imprinted polymers can be utilized in stereo- and regio-selective synthesis. These systems can be utilized, e.g. for peptide synthesis, by selectively coordinating reactants at a predetermined preformed cavity. Further, such polymers may be used for the selective removal of one enantiomeric species from solution, allowing reaction to be directed to another species in bulk solution leading to stereoselective and/or regio-selective synthesis in the cavity of for instance peptides. Additionally, when utilized as regioselectively interacting protectioning matrices, these polymers can direct reaction to an alternate centre of a reacting substrate.

  • Publication number: 20040043417
    Abstract: The present invention concerns a method for selectively establishing a dynamic combinatorial library of ligands for a target which binds at least two functionalities, which method comprises the following steps: selecting a plurality of functionalities which upon combination with each other ire capable of forming an entity which may bind to the at least two functionalities in the target; selecting at least one spacer group to be located between the at least two functionalities, which spacer group is of an appropriate size and/or flexibility to allow the functionalities to fit into the binding sites on the target and allowing a reversible bond formation and cleavage; creating discrete ligands by linking at least two identical or different functionalities by at least one spacer group or; linking the functionalities to fragments of the spacer group which contain functions allowing the said reversible bond formation under formation of the spacer group and cleavage of it; mixing together a plurality of different di

  • Publication number: 20040029172
    Abstract: The present invention deals with a method for the generation of a dynamic combinatorial library of ligands for a given target, capable of binding at least two functionalities, which method comprises the following steps: (i) selecting a set of n molecules carrying functionalities which may bind to the target, which molecules are capable of reversibly binding to each other under formation of an entity, n being an integer ≧1: (ii) mixing together said set of said n molecules: (iii) subjecting the mixture to conditions allowing a reversible bond formation and cleavage under formation of entities carrying different combinations of functionalities, until equilibrium is reached: (iv) optionally transforming the said entities into ligands: (v) repeating steps (i) to (iv) n-times, each time a different molecule of said set of n molecules being omitted: (vi) assessing the ability of each of the mixtures obtained to bind to a given target.
